'Islands' of regularity discovered in the famously chaotic three-body problem

When three massive objects meet in space, they influence each other through gravity in ways that evolve unpredictably. In a word: Chaos. That is the conventional understanding. Now, a researcher has discovered that such encounters often avoid chaos and instead follow regular patterns, where one of the objects is quickly expelled from the system. This new insight may prove vital for our understanding of gravitational waves and many other aspects of the universe.
